Un-create solid Brush?

I'm using CreateSolidBrush API for FloodFill affect. I was using the circle method to make some circles with the center transparent. After using Floodfill the circle is always filled with the backcolor of the form. Unfortunately the Circle method appears to have the same DC as the Window it's in so if I delete the brush I can't draw anymore on the window. So how do I make the brush transparent again. I can't do this through the circle method - it won't allow it now that I have created a "solid" brush. Can anyone figure this out?

Create a new transparent brush with the CreateBrushIndirect API, select it into a DC and delete the old brush.

Thanks! I'll give it a try
